A plurality of Integrated Devices are provided with an Internet connection and a telephone number. The telephone number has associated telephone connectivity via a telephone line, such that the Integrated Devices can be connected to by dialing the associated telephone number via telephones on the Public Switched Telephone Network (PSTN). The Internet connection has an associated Internet protocol (IP) address which is dynamically assigned when one device calls the telephone number of a called device via the PSTN. The dynamically assigned IP address for a first one of the calling or called device is provided to the other device, which initiates an Internet connection between them by sending an Internet message to the dynamically assigned IP address of the first device. Local and intermediate proxy servers perform dynamic IP address management, providing privacy and security for user IP addresses and data transmissions. Encryption keys are provided by PSTN digital messaging capabilities to calling and called devices for subsequent encryption of communications data transported across the Internet. The Internet is thereby integrated with the PSTN. Significant benefits, including the richness of Internet communications, become available by simply dialing the telephone number of suitably equipped devices or systems.
